Abstract (en)
[origin: WO2019197213A1] The invention relates to a manufacturing device (a1) for the additive manufacture of a three-dimensional object (a2), wherein the object is manufactured by applying layer after layer of a building material (a15) and selectively solidifying the building material, in particular by supplying radiation energy to points (a9) in each layer associated with the cross-section of the object in this layer, in that the points (a9) are scanned with at least one zone of influence, in particular a zone of influence of the radiation of a radiation beam (a22), and during operation the movable gas outlet (32) is associated with a reference process point (9) and/or with a target gas supply zone of the movable gas inlet associated with the reference process point in order to supply a flow of process gas to a target venting zone (22) of the movable gas outlet (32).
